[Detailed description of the invention]

[Field of Application of the Invention] The present invention relates to a method and device for transversely transporting containers that can centrally manage containers that are being carried into or out of a ship, mainly at a port, and can continuously carry out cargo handling operations. [Background of the invention] Generally, containers stacked at a port are carried onto a ship,
When loading into a trunk, etc., the container must be properly aligned. Conventionally, in order to move the container horizontally, a twist lock device was hooked to the corner hole of the container from the top using a hanging device (spreader), and the container was lifted and moved, or the container was held from below by a forklift and moved. This poses a problem in that it takes a lot of time to align the containers, but it also requires a lot of manual work, which makes the work less efficient and more dangerous. [Object of the Invention] The object of the present invention is to provide a method and apparatus for transporting containers in which a plurality of containers in which computers are transported are packed at the front with a constant distance of 1 t left between them and containers that are in contact with each other. to provide. [Summary of the Invention] The present invention provides a system in which guide rails and drive chains are arranged in parallel along a plurality of independently arranged driven chain conveyors,
A container cross-feeding device is mounted on this guide rail, and a clutch device 4':l is provided on this container cross-feeding device to connect and disconnect power transmission with the super-dynamic chain. The clutch mechanism is characterized in that the clutch mechanism is operated based on a command so as to stop the container behind each container 2 leaving a certain distance. According to the above-mentioned configuration, the position of each container and the empty space of the container on the driven chain conveyor are detected, and based on the detection results, [the moving chain and the container traversing device are connected or disconnected]. , the container is automatically front packed. [Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described based on the drawings. As shown in FIGS. 1 and 2, a large number of driven chain conveyors 2 are arranged in the longitudinal direction of the container.
supports the weight of The arranged driven chain conveyors 2, 2. A larger number of columns are arranged in the direction in which the container 1 is fed, and define the total length of the container 1 to be fed. The chain of the driven chain conveyor 2 meshes with both driven chain sprockets 5.5 disposed on the structure, has the function of supporting the weight of the container 10, and moves in accordance with the movement of the container 1. ing. As shown in the figure, the driven chain conveyors 2 are arranged independently next to each other, so that only the IrLCD chain conveyor 2 on which the container 1 is placed moves. ing. The driven chain conveyor arranged as shown in FIG. 911 2.2. . . . Guide rails 4, 4 are provided to guide the container traversing device so as to sandwich the container 1 in the feeding direction. A container cross-feeding device is mounted on the guide rail 4, and the container cross-feeding device 3 is designed to be able to suppress the container 1. Further, the container traversing device 3 will be explained in detail with reference to FIGS. 3 and 4. The container cross-feeding device 3 includes a pusher plate 6 that pushes the container 1, upper guide rollers 7.7, . . . that rotate by sandwiching the guide rail 4, and lower guide rollers 8, 8. ...and a clutch mechanism A. The clutch mechanism A includes a latch par 15 rotating around a support shaft 11, a latch release roller 9 provided at one end of the latch par 15, and a launch portion 12 provided at the other end. A drive chain] 3 is disposed vertically below the guide rail 4 so as to be flush with the guide rail, and the drive chain 13 is driven by a drive motor and a drive chain sprocket (not shown). A rice cake release roller guide 4' is provided below the guide rail 4, and while the container 1 is moving, the latch release roller 9 is moved from the rice cake removal roller guide 4'.
It is structured so that it rotates along the release roller guide 4' so as to be pressed against the lower surface of the roller. On the lower surface of the front release roller guide 4', there are stoppers at predetermined distances. : #E is provided. This stop mechanism B is such that a latch release member 10 can appear at any position at any time, and this latch release member]0 is controlled by a latch release control mechanism controlled by a computer. Next, the operation of one embodiment of the present invention will be explained. First, as shown in FIG. 3, when the latch portion 12 of the container traversing device 3 is latched to the drive chain 13, the container traversing device 3 moves toward the guide as the drive chain 13 moves in the direction of the arrow. It moves along the rail 4 and at the same time pushes the container 1 by the pusher plate 6 to move it. During this movement, the upper and lower guide rollers 7...
, 8... rotate so as to sandwich the guide rail 4,
The lunch release roller 9 rolls on the lower surface of the release roller guide 4'. Here, a latch member 10 is shaped so that the launch release roller 9 can ride on the lower surface of the release roller guide 4' located at the lower part of the guide rail 4.
appear. Then, e) the lunch release roller 9 at the bottom of the container traversing device 3 during operation is moved to the latch release member 10.
As a result, the launch release roller 9 is forcibly pushed downward, and the launcher 15 is moved to the latch support Il+.
Rotates counterclockwise around 11. Therefore, the latch portion 1 located at the other end of the latch 1i7I release roller 9
2 is rising

[7. The drive chain 13 is forcefully removed, and the movement of the feeder Q3 to the container 47 is stopped. As shown in FIG. 5, the control of the stopping machine 41' is performed by detecting the container cart placed on the driven chain conveyor 2 by a container position sensor and by computer control. That is, since the latch per 15 is always urged to rotate clockwise around the support shaft 11, the launch portion 12 is coupled to the drive chain 13, and the container on the right side in FIG. The container 1 is always traversed to the left by the container traversing device @3. When the container position sensor confirms that another container 1 is stopped in front of the container 1 that is being transported horizontally, a container detection signal is sent to the computer, and the computer sends a message indicating that the rear part of the container 1 that is stopped is detached. A signal is sent to the latch release control mechanism to cause the latch release member 10 to appear on the lower surface of the roller guide 4', and the latch release member 10 appears at the specified position.
Container l being fed horizontally like the container on the left in the diagram.
will stop behind the stopped container. Next, when the container placement locations in front of each of the container carts become empty, the container position sensor confirms that there is space in front of the container 1 and sends a signal to the computer. Contrary to the above, the computer sends a signal to the latch release control mechanism to remove the latch 1: removal member 10 that stops the container traversing device 3 of the container 1 located at the rear of the empty space, Since the latch release member 0 at the designated position is removed, the container 1 on the driven conveyor starts pail feeding, moves to the rear of the stopped container 1 in front, and stops. Therefore, each container is transported individually and moved so as to be packed in 1111, so that the container can always be kept in a state where it can be carried out. In the above embodiment, the launch detachment roller 9 is urged upward, and the launch part 12 is connected to the drive chain 13 by removing the launch detachment member 10, but the urging force is not always necessary. Instead of d, as shown in FIGS. 3 and 4, a detachment roller guide 4'' is further provided below the detachment roller guide 4', and only the lower part of the appearance of the anti-disengagement member 10 is removed. The detachment is performed as in the previous embodiment, and the launch can be coupled by the launch detachment roller 9 riding on the detachment roller guide 4''. FIG. 7 shows a container transfer management system using the above-mentioned container cross-feeding device. The structure 23 is placed on the driven conveyor 21, packed to the right by the feeding device into the container (l'), and is sequentially moved to the structure 23 by the crane 14.
It is loaded onto a truck 22 parked below and transported out. In this embodiment, the container feeding was explained as an operation in only one direction, but the driven conveyor and the container lateral feeding device
It is also possible to transfer the container in the opposite direction by reversing the above direction. In this case, the truck can be loaded onto the ship. In the embodiment, the container cross-feeding device is controlled by a computer, but it does not necessarily have to be controlled by a computer, and the latch release member 10 is made detachable so that it can be freely inserted or removed manually. By doing so, the container traversing device can be controlled without requiring any force. [Effects of the Invention] As described above, according to the present invention, the number of containers on the conveyor can be automatically front packed and stopped, so that efficient cargo handling work can be performed. Adding a container to Mano,
Continuous unloading improves the operating efficiency of the conveyor.
